This invention relates to fiat work ironers for laundry use andparticularly to padded rolls therefor. I 1 v In pressing or ironinglaundered articles it has been the practice to lie rollsand heatedironing beds betwee vhich the articles are. passed in producing theironing finish. Up to the present time the most satisfactory type ofroll is one comprising a suitable cylindrical core and a cellulosepadding arranged thereon and adapted to press the articles with uniformtension against the ironing bed. These rolls possess a very distinctdisadvantage in the fact that it is necessary to wind the cellulosepaddingupon the core and when wound in this way the rotation of the rolltends to wrap the padding tightly upon the core and in a very shorttime," due to this wrapping action and the heat and;

moisture, the padding becomes hard and does not produce the necessaryresiliency and perimeter to be concentric with'the shaft.

rough dry spots appear on the work, especially at the seams andthickened portions. To overcome the foregoing, the present invention hasbeen devised and it consists of an ironing machine wherein the heatedironing beds are supplied with rolls comprising cores and rubbercoverings circumferentially continuous and extending throughout thelength of the roll. The roll thus produced, includes a core of a typesuchthatdts size or thereafter increased to size in a concentricarrangement to thoroughly grip the covering and support it radially atall points throughout its length so that it may not only act as a paddedroll for these machines, but includes means which insures the driving ofthe covering by the core. The invention also contemplates a specificform of rubber covering in the form of an annular tube with an innerre-enforcement for maintaining its shape-and for permitting the corestructure to be increased in size or otherwise arranged to properlysupport the tube radially throughout its length and furnish a drivebetween the two.

Other features of the invention will be brought out in the followingdescription, drawings and claims.

Referring to the drawings, Fig. 1 is a side elevation of the rollconstructed according to my invention with parts broken away;

In the embodiment shown, 1 represents a suitable shaft carrying radiallyextendingarms or webs 2 having peripheral plate portions 3 riveted orotherwise secured to the the length of the roll and arranged on eac sideof the opening. Enga ing the side walls of the slit or slot in the s ell4 is a suitable cam rod 7 mounted at its ends in suitable end plates 8secured to the shaft 1. At the end of this cam rod 7 is a suitable nut 9or other device for rotating the cam rod. When the cam 01 rod isturnedit spreads the shell and thereby increasesits size or When it iscollapsed the shell is somewhat an Fig. 3 1s a s m lar view showing amodi-.

eccentric and smaller in size and perimeter so that it may pass freelywithin the covermg.

The roll cover is in the form of a circum- I forcing wire 12-woundspirally throughout the length of the roll during its productionl Uponthe outside of this re-enforcing inner structure is a suitable cover13of rubber of the proper thickness to bring the roll to size. Thiscover is built up beforethe rubber content is vulcanized and aftervulcani zation it presents a covering or padding comprising an innersupporting re-enforcement and an outer resilient pad portion suitablytreated to produce the desired ironed resilieney and be unaffected bythe heat incident to the ironin operation.

The roll thus produced is then covered with a small amount of cellulosepadding in the form of a cover cloth 14 wound in several turns about theroll.

In the modification shown in Fig. 3 the outer pad portion 13 is providedon its outer face with a textile fabric coating 15 imbedded in the outersurface of the roll whileit is a circumferentially continuous tubularpad still green, and held tightly in place by the member consisting ofan inner annular rcprocess of vulcanization.
